Abstract
An output current of a transistor can be predicted by a method of the present invention. A direct current amplification factor H.sub.FE (I.sub.D) of the transistor is varied depending on the output current. H.sub.FE0 is a direct current amplification factor of the transistor at a predetermined output current. H.sub.FE (I.sub.D)/H.sub.FE0 is drawn on a graph. A value of an output current at a driving voltage is obtained by regarding the factor as a predetermined value. The value is plotted on the graph and a straight line is drawn between the plotted value and an origin of the graph. An output current at an intersection of a curve of H.sub.FE (I.sub.D)/H.sub.FE0 and a straight line.
